Potent odorants in Native spearmint, Scotch spearmint, and Macho mint oils were determined by the combined use of gas chromatography-olfactometry (GCO), gas chromatography-mass spectrometry (GC-MS), and aroma extract dilution analysis (AEDA). Of the 85 odorants detected, ( R)-(-)-carvone was the most potent odorant in all three spearmint oils. Additional predominant odorants in all spearmint oils included eugenol, ethyl ( S)-(+)-2-methylbutanoate, ( E)-β-damascenone, and (3 E,5 Z)-1,3,5-undecatriene. Forty-six compounds were quantitated using various methods, including 19 by gas chromatography with flame ionization detection (GC-FID), 20 by stable isotope dilution analysis (SIDA), and 14 by GCO dilution analysis. Concentrations were used to calculate the odor activity values (OAVs) for predominant odorants in the oils. Among the compounds quantitated, those with the highest OAVs were ( R)-(-)-carvone, 1,8-cineole, ( E, Z)-2,6-nonadienal, ( E)-β-damascenone, and (3 E,5 Z)-1,3,5-undecatriene.
采用气相色谱-嗅觉测量法（GCO）、气相色谱-质谱联用（GC-MS）和香气提取物稀释分析（AEDA）联用的方法，确定了原生薄荷、苏格兰薄荷和 Macho 薄荷油中的强气味物质。在所检测到的 85 种气味物质中，（R）-（-）-蒈烯是这三种薄荷油中最强烈的气味物质。在所有薄荷油中，其他主要气味物质还包括丁香酚、乙基（S）-（+）-2-甲基丁酸酯、（E）-β-大马酮和（3E，5Z）-1,3,5-十一烷三烯。使用各种方法定量了 46 种化合物，包括 19 种用火焰离子化检测的气相色谱法（GC-FID）、20 种稳定同位素稀释分析（SIDA）和 14 种 GCO 稀释分析。用浓度计算了油中主要气味物质的气味活度值（OAV）。在所定量的化合物中，OAV 最高的是（R）-（-）-蒈烯、1,8-桉叶素、（E，Z）-2,6-壬二烯醛、（E）-β-大马酮和（3E，5Z）-1,3,5-十一烷三烯。
